How to apply fertilizer to flowers
Flower cultivation needs timely recovery of fertilization materials, and its fertilizer application methods are various. However, different methods have their own advantages and disadvantages. They should be selected according to the different conditions of flower growth.
Chong Shi: In conjunction with the watering of the flowers, the quantitative chemical fertilizer is sprinkled in the ditch and melted, and the water is sent to the soil around the root of the flower. With this method, the disadvantage is that the fertilizer can easily leak and leak in the channel, and can also leak into the deep layer that the root system cannot reach, resulting in waste. The advantage is that the method is simple and it can be used when there is sufficient fertilizer source, large crop cultivation area and labor shortage.
Embedding: Ditching and digging pits between plants and lines of flower plants and applying chemical fertilizers to fill the soil. Using this method to reduce fertilizer waste, but the large amount of labor, labor, but also need to pay attention to buried trench pit to be more than 10 cm away from the crop stem base, so as not to damage the root system. Usually this method can be used during the winter season, when the labor force is sufficient and the crop growth is not large. This method can also be used during the peak of flower growth. However, in order to prevent the occurrence of side effects such as burning seedlings, it is necessary to water after planting to make the fertilizer. The concentration decreases. This method is less wasteful on fertilizers, but it requires a lot of labor and labor, and it should prevent burning of seedlings after burying in places where water is scarce.
Spreading: After the rain or in combination with watering, dampness spreads the fertilizer between the rows of flowers. Although this method is simple, there is still a part of the fertilizer will lose volatilization. Therefore, it should only be used in the case of inconvenient operations in the field and the need for flowers to be fatter. In production, ammonium bicarbonate fertilizer is very volatile and it is not appropriate to use this method of application.
Drip Irrigation: Install the fertiliser at the place where the water source enters the drip irrigation pipe, dissolve the fertilizer in the fertiliser, and insert the drip irrigation pipe into the suction pipe filter of the fertiliser. The fertilizer can then automatically enter the soil around the root of the crop with watering. With the plastic film covering, the fertilizer will hardly volatilize or be lost, but it will also save labor and work well. However, this method requires the mulching of the mulching, and it must have supporting drip irrigation and tap water equipment.
Intubation application: This fertilization technique is mainly applied to woody, vine and other plants. In use, different fertilizer formulations should be selected for the different needs of different plants. This method is easy to apply fertilizer, high fertilizer utilization, can effectively reduce fertilizer input costs. The cannula is manufactured by taking one plastic tube with a length of 20 to 25 cm, a diameter of 2 to 3 cm, and a tube wall thickness of 3 to 5 mm. The bottom of the plastic tube is made into a conical shape, which is easy to insert into the soil. A small round hole with a diameter of 1 to 2 mm is evenly drilled around the plastic tube (including the lower cone). The top part of the plastic tube is covered with a slightly larger plastic tube to prevent rain from splashing into the tube. The method of infiltration is: after the cannula is made, the nitrogen, phosphorus and potassium can be rationally mixed (generally according to the ratio of 8:12:5) into the intubation according to the different needs of different flowers for fertilizer elements. And cover. The plastic tube is then inserted into the soil 5 to 10 cm from the root of the flower. The top of the plastic tube is exposed to 3 to 5 cm of soil so that the plastic tube can be taken out for viewing or changing the compound fertilizer. When the plastic cannula with mixed fertilizer is inserted into the soil, the moisture in the soil can be gradually penetrated into the plastic tube through the small circular holes of the cannula to decompose the fertilizer. Fertilizer decomposition products continue to feed through the small round holes in the soil.
Outside the root dressing: that is, foliar spray fertilizer, can be combined with spraying outside the root dressing. This method uses less fertilizer and has quick effect. It can also prevent the fertilizer from being fixed by the soil. It can be used in the absence of obvious nutrients and the roots of the flower growing at the late stage of growth. It can show its advantages, except that potassium dihydrogen phosphate, urea, potassium sulfate, Potassium nitrate and other commonly used large amounts of elemental fertilizer, there are also suitable for a large number of elements and trace elements or contain a variety of amino acid composition of fertilizers, such as phytoalexin, spray Shibao, Yemian Bao and so on. The basic nutrients needed for the growth and development of flowers are mainly derived from basal fertilizers and other fertilizers that are applied top-up. Extra-root fertilizers can only be used as an auxiliary measure.
Some traditional Chinese medicines are processed from insects. These kind of insects have high medicinal value, and we collect them when they are dead and use the medicinal way to process the whole body. They also plan an important role in traditional Chinese medicine area. Such as CICADAE PERIOSTRACUM and SCORPIO.
